On the note of protecting stuff... we did a costume workshop at the Star Wars: Where Science Meets Imagination exhibit. I looked a way for a moment, then came back to see someone walking off wearing my Fett helmet!
I went over to the kid, probably about 16, and rather aggressively recovered my property. He claimed that the thought that it was ok to take, since it was out on the table.
On the flyer note... that's definitely a good thing. The costume pricing one has been really popular, as have the general recruiting ones.
I think for TDH, making something up based on the "how much will you spend" thread would be ideal. It would be great for the folks that are really into it, and would save other people the trouble of getting all excited about doing it, then realizing how much time and money goes into it.
